External Email - Use Caution Yes, when I import the original file (lh.pial) and the converted .vtk file (lh.pial.vtk) in Freeview, there is a mismatch. I am using the vtk pial file in a C++ application to visualize the brain. Now I want to import the CT NIFTI into this application to extract the iso-surface using a marching cubes algorithm. In order to avoid transformation matrices etc. it would be great to process the CT NIFTI in such a way that it matchs the converted vtk files.
Thanks for your help. ________________________________ Von: [email protected] <[email protected]> im Auftrag von Bruce Fischl <[email protected]> Gesendet: Montag, 3.

And what are you intending to do with the CT? Maybe you are better off sampling it onto the surface than trying to map the surface onto the CT? On Mon, 3 Sep 2018, M.
